Electric out

Fossil Fuels or their synthetic equivalents will be around a long time before batteries strong enough to power a residence for extended periods will be developed.

I mean they're not cheap, but they have been around for a while.


13KWh a piece, can stack up to 10. My cousin has two paired with a modest solar setup (I think it's around 4KW) because his house loses power every time a mouse farts within 2 miles of the property. House is around 1500sqft and this setup will run his whole house (with heatpump) for a week or more even when overcast/cloudy so the panels are only minimally recharging the batteries.

I bought his Honda 3500 genny before he left for the west. That thing is just unbreakable.
One of the BEST generators ever made , mine is about 25 years old never missed a beat ! Runs about 10 hours on 8 gallons of fuel . Just run it dry when using todays crappy gas.

Where does he live Bermuda ?

Great power equipment. I have a 650 W super quiet I bought 30 years ago on the boat and a 2,500 W construction gen I bought in the late 90's. Nothing ever needed but oil changes.

Would have it worked yesterday with the very dark day and several inches of snow?

In MD I heard you are not allowed to be off the grid.

Going to get me the 500w version to power a lamp, wifi and laptop for power outages.

Do they have a setup where you simply plug it into a 120V/240V outlet and charge until needed? Would make a lot more sense than limiting it to solar installations. And their web pages are crappin' useless.

New Mexico. Gets fairly warm in the summer but usually not much higher than 100, and they get snow in winter. House is a recent built pre-fab single level (basically a square) with decent insulation, so I imagine it's pretty energy efficient.

Perfect scenario. Probably wouldn't work in several days of very dark in a row, but would have got him through a day or two until some minimal sun or the power comes back on. He didn't buy it to go off-grid, just to even out their frequent several hour power outages. They have buried power lines too so I don't know why his power goes out all the time.

I know people buy them without solar just for power management. In some places (like in California) where they charge different prices depending on the time of day they can actually be a good investment as well (charge at night and use during the day). I don't think you can just plug them in, they have a controller that needs to be wired to the panel if you want them to automatically switch over. That said, there are several companies with similar products. Might find one that's just plug-in and then manually turn on (after you flip your main breaker of course) to back feed. I wouldn't do that on a 110 line though, maybe a 220 30A circuit if your planning to run a modest HVAC. Anything else could probably go over a normal electric dryer connection (220v 15A).

By off grid I mean if the power is out the solar can't power your house because they were worried it might feed back into the grid and be a safety hazard. I don't know if that's still the case or if they allow it with some sort of automatic safety switch.

There's a couple of different connection schemes, one being an ATS (automatic transfer switch) which works very much like an ATS for whole-house generator backup.

The nice thing about the ATS for battery systems is that you are always running from the battery and after an event it switched off the grid power (vs being on grid and after event switching on the backup power). So no interruptions and you have very clean power for your devices (no need for surge protectors in the house).
